Subject: [PATCH] extcon: Fix kernel hang for find_cable_index_by_name() users
Date: Mon, 6 Jul 2015 15:31:29 +0300	[thread overview]
Message-ID: <1436185889-773-1-git-send-email-rogerq@ti.com> (raw)

Users of find_cable_index_by_name() will cause a kernel hang
as the while loop counter is never incremented and end condition
is never reached.

Fixes: commit 73b6ecdb93e8 ("extcon: Redefine the unique id of supported external connectors without 'enum extcon' type")
Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
